For a man shall not withhold his hand from slaying his sons and his sons’ sons, And the sinner shall not withhold his hand from his honoured brother: From dawn till sunset they shall slay one another.
Background and history of Book of Enoch (1 Enoch), and issues with this book.
R. H. Charles, The Book of Enoch (London: SPCK, 1917), public domain. The verse text is the English Wikisource transcription of that translation. Charles’s editorial signs are kept. He rearranges some verses in chapters 5, 39, 90, 91, and 106, so those chapters are not a straight 1, 2, 3 sequence.
